Add LibreOffice security advisories importer

NucleiAv · NucleiAv · commit 49cf20bd6ae5 · 2026-03-14T00:06:12.000-04:00
Fetches CVE IDs from the LibreOffice advisory listing page and retrieves structured data (CVSS, CWE, references, dates) from the CVE 5.0 JSON API at cveawg.mitre.org. Fixes: #1898 Signed-off-by: Anmol Vats <anmolvats2003@gmail.com>
